摘　　要：固体氧化物燃料电池(SOFC)是一种以优异的能量转换效率而闻名的电化学技术.传统SOFC的应用受到其高温(800~1000℃)工作的限制,长期在高温下工作会导致电极材料性能衰减,因此,将其工作温度降到中低温,并提高电池的耐用性,成为SOFC研究的主要关注点之一.但是,工作温度的降低会导致电极的极化损耗急剧增大,电池性能快速下降.电极的极化损耗主要来源于阴极的极化损耗,因此,在中低温减小阴极的极化损耗和提高阴极材料的性能成为关键.本文综述了近年来中低温SOFC阴极材料的研究进展,并总结了这些材料在中低温运行中存在的问题和未来的发展方向。Solid oxide fuel cell(SOFC)was an electrochemical technology known for its excellent energy conversion efficiency.The application of traditional SOFC was limited by its high temperature(800-1000℃),and long-term operation at high temperature will lead to the attenuation of the performance of electrode materials.Therefore,reduced its working temperature to medium low temperature and improved the durability of cells have becom one of the main concerns of SOFC research.However,the decrease of the working temperature will cause the polarization loss of the electrode to increased sharply,and the cell performance will decline rapidly.The polarization loss of the electrode mainly comeds from the polarization loss of the cathode.Therefore,it was critical to reduce the polarization loss of the cathode and improve the performance of the cathode material at medium and low temperatures.The research progress of SOFC cathode materials at medium and low temperature in recent years was reviewed,and the existing problems and future development direction of these materials in medium and low temperature operation have been summarized.
